QCGPU-Rust

Open Source, High Performance & Hardware Accelerated, Quantum Computer Simulation in Rust

Features:

  • Uses OpenCL kernels
  • Runs cross platform
  • Simulation of arbitrary quantum algorithms
  • Optional simulation of decoherence
  • Optimized for maximally entangled states
  • Accelerated with GPUs
  • Includes Example Implementations of Grover's algorithm, the Deutsch-Jozsa algorithm, the Bernstein-Vazirani algorithm and Shors algorithm
  • Implements Hadamard, Pauli and phase gates, with support for arbitrary single qubit gate creation
  • Support for controlled gates along with the toffoli and swap gate
  • Support for measuring a state many times quickly

Prerequisites:

  • OpenCL (Ensure that an OpenCL library is installed for your platform and that clinfo or some other diagnostic command will run).
  • Rust (install here). Please use a nightly build.

If you wish to run the benchmarks, you must also install libquantum and qiskit.

  • Libquantum can be installed from source, or from a package manager such as brew (brew install libquantum --devel) or apt (sudo apt-get install libquantum-dev). You should get the development version 1.1.1
  • Qiskit can be installed through pip pip3 install qiskit.

Usage

First, add the crate to cargo.toml

[dependencies]
qcgpu = { git = "https://github.com/QCGPU/QCGPU-rust" }

Then just use the crate!

extern crate qcgpu;

fn main() {
    let mut state = qcgpu::State::new(2, 0);
    state.apply_gate(0, qcgpu::gates::x());

    println!("Measured: {}", state.measure());
    // 1
}
